Hey there! As a supplier of lab diamond jewelry, I'm super stoked to chat with you about the different shapes of lab diamonds used in jewelry. Lab diamonds are becoming more and more popular these days, and for good reason. They're just as beautiful as natural diamonds, but they're more affordable and have a much smaller environmental footprint.
So, let's dive into the world of lab diamond shapes. There are quite a few options out there, each with its own unique charm and style.
Round Brilliant Cut
The round brilliant cut is hands - down the most popular shape for lab diamonds in jewelry. It's been around for ages and is the classic choice for engagement rings and other high - end pieces. The way a round brilliant cut lab diamond is cut, it has 58 facets, which are like little mirrors that bounce light around inside the diamond. This gives it that amazing sparkle and fire that we all love in diamonds.
You can find round brilliant cut lab diamonds in all sorts of jewelry. For example, a Lab Created Diamond Gold Pendant Necklace with a round center stone looks incredibly elegant and timeless. It hangs low on the neck and catches the light with every movement, making it a real eye - catcher.
Princess Cut
Next up is the princess cut. This is a square - shaped diamond with pointed corners. It's a modern and trendy choice, and it's growing in popularity really fast. Princess cut lab diamonds are great because they have a lot of brilliance, just like round diamonds, but they also have a different kind of look. The sharp edges give them a more angular and contemporary feel.
If you're into earrings, Lab Diamond Drop Gold Earrings with princess cut lab diamonds are a must - see. The square shape creates a bold and stylish statement, especially when paired with the shine of gold.
Emerald Cut
The emerald cut is a very sophisticated and elegant option. It's a rectangular - shaped diamond with step - like facets. Instead of the flashy sparkle of the round or princess cut, the emerald cut has a more understated, calm look. The long, straight lines give it a regal appearance, making it perfect for formal jewelry.


You'll often see emerald cut lab diamonds in classic pieces like diamond tennis bracelets. A Lab Grown Diamond Gold Tennis Chain with emerald cut diamonds is a symbol of luxury and refinement. It's great for adding a touch of class to any outfit.
Oval Cut
Oval cut lab diamonds are another great choice. They're sort of like a rounded version of the emerald cut. Ovals are known for elongating the finger when used in a ring, which is a big plus for a lot of people. They also have a beautiful sparkle and a unique shape that stands out.
Oval cut lab diamonds can be used in all kinds of jewelry, from pendants to rings. They look great in both simple and elaborate settings, so you can really get creative with how you style them.
Pear Cut
The pear cut is a combination of the round and marquise cuts. It has a rounded end on one side and a pointed end on the other, kind of like a teardrop. Pear cut lab diamonds are very romantic and feminine. They're often used as the center stone in engagement rings or in pendant necklaces.
When you use a pear cut lab diamond in a pendant, it creates a lovely, flowing look that seems to move with you. It's a shape that really catches the eye and adds a touch of glamour to any piece of jewelry.
Marquise Cut
The marquise cut is an elongated shape with pointed ends. It's a very dramatic and stylish cut. Marquise cut lab diamonds can make a piece of jewelry look bigger because of their long shape. They're also known for having a lot of brilliance.
You can find marquise cut lab diamonds in rings, earrings, and bracelets. They add a sense of drama and sophistication, making them perfect for special occasions or for someone who wants to make a bold fashion statement.
Heart Cut
Last but not least, the heart cut. This is the ultimate symbol of love and romance. Heart cut lab diamonds are shaped exactly like a heart, with a cleft at the top and a point at the bottom. They're not as common as some of the other shapes, but they're incredibly special.
A heart cut lab diamond in a pendant or an engagement ring is a beautiful way to show someone how much you care. It's a unique and sentimental choice that's sure to be cherished.
